One of the key failures, according to Allen, is that we try to educate people to think like ourselves. 
Roland Allen says:
We educate our converts to think, as we, accustomed to a long-established and highly-organized church, naturally think, that none but duly appointed ministers may preach.We dread the possible mistakes of individual zeal. The result is that our converts hesitate to speak of religion to others. They throw the responsibility upon the licensed evangelist and ‘the mission’. They do not feel any responsibility themselves to evangelize the world. Their mouths are closed. Here and there, of course, we find a man so full of the Spirit of the Lord that he cannot hold his peace, but he is a comparatively rare exception (Roland Allen, Missionary Methods: St. Paul’s or Ours? Grand Rapid, MI: Eerdmans Publishing Co., 1962, p. 94).
Various China watchers have said that the best thing that happened in China was Mao. The missionaries had to leave and could no longer control who would preach and who would not preach. They no longer had control over how to organize Christ’s church. The Holy Spirit took over and began to use all and every fiery soul that wanted to speak in His Name. If you haven’t read the book The Heavenly Man by Brother Yun (with Paul Hattaway) you really need to read it. God’s work is incredible. We just must make sure that we don’t get in the way of His work. And I know from experience that “getting in the way” is really easy to do.
